| 摘 要： | 二连盆地形成于侏罗纪到早白垩世期间，是东北亚断陷盆地系内的一个典型的盆岭式断陷盆地群，其内蕴藏丰富的煤和油气资源，综合分析了二连盆地油气勘探中积累的地质资料，系统地研究了与盆地形成有关的构造，并与北美西部盆岭省进行了对比，揭示了二连盆地宽裂陷作用和低拉伸率条件下的伸展构造系统。以上述研究和前人的研究成果为基础，探讨了盆地发育的深部背景。

| Abstract: | Erlian fault basin group, a typical basin and range_type fault basin group, was formed during Late Jurrasic to Early Cretaceous, in which there are rich coal, oil and gas resources. In the present paper the abundant geological and petroleum information accumulated in process of industry oil and gas exploration and development of Erlian basin is comprehensively analyzed, the structures related to the formation of basin is systematically studied, and the complete extensional tectonic system of this basin under conditions of wide rift setting and low extensional ratio is revealed by contrasting with basin and range province of the western America. Based on above study and achievements of former workers, the deep background of the basin development is treated. |
